@taichou115030 again it is not practical, he has no knowledge of the land and the world, him venturing out to unknown places would endanger him, specially without the support of the clan. Plus there is no certainty of him making enough money for a living, since all merchants so far follow regular trades and don't venture too out of their comfort zones.
There is no single way of tackling the issue of travelling back home, his way of doing it perfectly valid and fits his character of wanting to repay the clan while also getting information from others. Why you say he isn't trying enough is beyond me, since obviously he isn't expecting to go back within a few years and probably has a longer timeframe in mind, as he already has heard of other people who have remained and even founded countries here.
You have to realize that people cannot just suddenly start travelling the world on a caravan, he is no isekai op hero with cheat skills.
